CT images of the brain are conventionally viewed from below, as if looking up into the top of the head. This means that the right side of the brain is on the left side of the viewer. The anterior part of the head is at the top of the image. CT brain - image orientation Hover on/off image to show/hide findings Click image to align with top of page Edit article Citation, DOI, disclosures and article data This article lists a series of labeled imaging anatomy cases by body region and modality. Brain CT head: non-contrast axial CT head: non-contrast coronal CT head: non-contrast sagittal CT head: non-contrast axial with clinical questions CT head: angiogram axial CT head: angiogram coronal Key points Grey matter appears grey White matter appears blacker The brain consists of grey and white matter structures which are differentiated on CT by differences in density. White matter has a high content of myelinated axons. Grey matter contains relatively few axons and a higher number of cell bodies. CT Brain Anatomy Skull bones and sutures Key points Main skull bones - frontal, parietal, occipital, ethmoid, sphenoid and squamous temporal Main sutures - coronal, sagittal, lambdoid and squamosal Injury to the pterion area may lead to formation of extradural haematoma due to injury of the middle meningeal artery

The brain is surrounded by cerebrospinal fluid (CSF) within the sulci, fissures and basal cisterns.CSF is also found centrally within the ventricles.The sulci, fissures, basal cisterns and ventricles together form the 'CSF spaces', also known as the 'extra-axial spaces'. CSF is of lower density than the grey or white matter of the brain, and therefore appears darker on CT images. CT Brain AnatomyGrey matter structures. The cortex, insula, basal ganglia and thalamus are the important grey matter structures. Important grey matter structures visible on CT images of the brain include the cortex, insula, basal ganglia, and thalamus. CT head (sometimes termed CT brain ), refers to a computed tomography examination of the brain and surrounding cranial structures. It is most commonly performed as a non-contrast study, but the addition of a contrast-enhanced phase is performed for some indications. This article covers non-contrast and delayed post-contrast imaging. Different areas of the brain are supplied by the anterior, middle and posterior cerebral arteries in a predictable distribution. The posterior fossa structures are supplied by the vertebrobasilar arteries.. The arteries of the brain are not well visualised on conventional CT, but a knowledge of the areas of the brain they supply is helpful in determining the source of a vascular insult.

Key points. White matter of the brain lies deep to the cortical grey matter. The internal capsules are white matter tracts which connect with the corona radiata and white matter of the cerebral hemispheres superiorly, and with the brain stem inferiorly. The corpus callosum is a white matter tract located in the midline. IMAIOS and selected third parties, use cookies or similar technologies, in particular for audience measurement.

The cerebellum (infratentorial or back of brain) is located at the back of the head. Its function is to coordinate voluntary muscle movements and to maintain posture, balance, and equilibrium. More specifically, other parts of the brain include the following: Pons. CT Brain ct Axial non-contrast C+ delayed C+ delayed C+ delayed Brainstem and cerebellum without evidence of focal lesions. Lateral ventricles of normal volume. Third and fourth ventricles in midline. Basal subarachnoid cisterns normal configuration. Focal abnormalities are not observed in the brain parenchyma.
